Lem-s Patent No. 100,075, dated February 22, 1ero.

IMPROVEMENT IN SASH-HOLDERS.

The- Echedule referred to in these Letters Patentand making part of the same.

To all 'whom it may concern Be it known -that I, CHARLES W. RocKHoLD, ot"

the city of Peoria, in the county of Peoria, and in the Slate of Illinois, have -invented a new and improved l Sash-Fastener and Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which- Figure 1 represents a perspective view.

Figure 2 is Ia side view of same, showing use of turn-key. v

Figure 3 is an end view of turn-key.

`Figure 4: is au elevation of cams, showing use of push and draw-keys.

Figures 5 and 6 are views in detail of the halves of case in juxtaposition. y

Figure 7 'is a sectional view in detail of cams.

Figure 8 is a view in detail of swinging cover of key-hole.

Like letters in the di'erent figures of the drawings indicate like parts.

rlhis invention relates to providing either windowframes or window-sash with adjustable fasteningsto sustain aud'lock the sash at any height, and be let either into the sash or into its' channel. This-lock may belet either into the sash channel or into the sashv itself with equal advantage.

It consists of a metallic case, O D, in one of which are pivoted two cams, A B, whose heads a a project slightly above the surface of the case, and are kept asunder in that position by a spiral spring, i, which causes the points of the segmental heads a of eachcam to bite the opposing wood-work, either of sash or channel of jamb, according as it may e placed.

The cams consist each of two arms, a b a d, uniting at a right angle, at whichpoint they are each pivoted, about one inch asunder, tothe case D, by pins gg, either cast on one of plates D or ou the angle of cams. llhe inner arms b d, when the cams are sustaining the sash, meet 'at an angle within the line of the pivots and the segmental heads of the cam, one of them having a pin, e, cast on it, projecting across the interior of lock to the outside, the corresponding point of the arm bof the other cam A having a slot, f, which passes into the pin e.

A thumb-key, J, with the outward end bent at a right angle, and having several holes or notches on its inner end, runs through a slot, h, in the face of the l case, and embraces the pin c, the common point of union of the arms of cams. The segmental heads of each cam finish in a slight ciu-ve, the surface of which is either smooth or serrated, tangential to the arc described by the posterior ends of theheads, so that the act of closing them together brings their points to a level with or below thesurface of metal case, and releases the wood-work.

or equivalent device on the part of the A nipple, u,

retains a spiral neck of each cam facing each other,

spring, i, which keeps thecams in bitingaction undue separation being prevented by the ends of the cases behind each cam. Y Y

The lock is let into a mortise in the sash itself', or

into the channel G, in which the sash runs. The latv ter plan is that described above. In the former case the key J is reversedl or inserted through a mortise i n the sash-frame, from near the surface ot' glass, and

passes to the pin e, which key, in thismode of apply` ing the-lock, has to be pulled to act on the cams. The lock, too, in this case, is of course let into the wood.

work of thesash. The notches in the key are to suit various thicknesses of wood-work.

Fig. 4 illustrates both the draw and the push-key plans. The draw and push style of key may be dispensed with by cutting a key-hole into the wood-work over the pin e which unites the cams, and inserting'a key, I, of the ordinary shape, with a recess, k, inthe ward which will lit onto the pin, and a swinging cover, m, to clasp shank of key, will cover the key-hole, and at vthe same time steady the key in unlocking and keep out dust, and the key be withdrawn entirely, if

desired.

The end of the shank of the key has a small nipple, -l, which fits into a corresponding hole, l, in the case C. The advantages of this invention are that it securely locks the sash at any required angle; also, that it can be used with great facility either mortised in sash or int-o the window channel;l also, that it can be locked with a press-key or latch, with a draw-key, or a turnkey, with equalfacility.

Haring thus fully describedA my invention,

What l claim therein as new, and desire .to secure by Letters Patent, is-

The sashflock and fastener C D, consisting of cams A B, with arms b d, the arm b of the one having a slot embracing pin e of arm d of the other, in combination with spiral spring i, constructed,applied, and

operated either by a turn, draw, or push-key, Asubstan-v tially as described. Y

In testimony that I claim the foregoing, I have hereunto set my hand'this 30th day of September', 1869.
